Anyone else ?

I am noticing sometimes my leg or arm feels like it is going numb but its a stabbing type stinging pain. Not when your foot falls asleep and it feels tingley cause it isn't like that at all. It hurts and bothering me alot. I am pregnant i dont know if that is a side affect lol but i dont have any tight clothing on or hair ties or anything on my arms or legs to make this happen. Could is also be the weather? i have to take tylenol in order for the pain to go away but it still comes back randomly. anyone else ? or anyone know what this could be ?
